This module allows you to spawn processes, connect to their
input/output/error pipes, and obtain their return codes.
For a complete description of this module see the Python documentation.
Main API
========
run(...): Runs a command, waits for it to complete, then returns a
CompletedProcess instance.
Popen(...): A class for flexibly executing a command in a new process
Constants
---------
DEVNULL: Special value that indicates that os.devnull should be used
PIPE: Special value that indicates a pipe should be created
STDOUT: Special value that indicates that stderr should go to stdout
Older API
=========
call(...): Runs a command, waits for it to complete, then returns
the return code.
check_call(...): Same as call() but raises CalledProcessError()
if return code is not 0
check_output(...): Same as check_call() but returns the contents of
stdout instead of a return code
getoutput(...): Runs a command in the shell, waits for it to complete,
then returns the output
getstatusoutput(...): Runs a command in the shell, waits for it to complete,
then returns a (status, output) tuple

CalledProcessErrorzRaised when run() is called with check=True and the process
returns a non-zero exit status.
